GRP Fibreglass Flat Roofing in Waterbeach

Waterbeach is a fen-edge village north of Cambridge where a large new town is being built on the former barracks site, alongside the older village homes. We work on both period roofs and modern concrete tile and flat roofs here.

GRP, or glass reinforced plastic, is a polyester resin reinforced with chopped glass fibres to form a tough, waterproof laminate. It was first widely used for boats because it is flexible and does not corrode, and it is now one of the most popular flat roofing systems.

Our GRP roofs are typically built from a single-ply GRP laminate over an 18mm OSB3 deck, finished with GRP edge trims and a protective topcoat. Finished this way, the roof is lightweight and seamless, copes well with hot and cold weather, and can last more than 20 years.

Most GRP roofs are finished in grey, but other topcoat colours are available if you want the roof to match your property. For a free GRP roofing quote in Waterbeach, call 07467 757 367.

Where We Fit GRP Roofs in Waterbeach

Flat Roof Replacement

We strip old felt or failed coverings, renew the deck where needed and lay a new GRP roof.

Porches and Bay Roofs

Small flat roofs over porches and bay windows can be finished in GRP with matching edge trims.

Garages and Outbuildings

Replace tired felt on garages, sheds and outbuildings with a GRP roof that needs very little maintenance.

Dormer Roofs

GRP is lightweight and easy to form around upstands, making it well suited to dormer roofs on loft conversions.

Balconies and Roof Terraces

With the right deck and topcoat, GRP can create a hard-wearing waterproof surface for balconies and terraces.

Extension Roofs

Kitchen, rear and side extensions with flat roofs are ideal for GRP, giving a neat, seamless finish.

Why Waterbeach Properties Need the Right GRP Fibreglass Roofs

Plenty of newer homes around Waterbeach have single-storey sections that suit a GRP fibreglass roof: rear extensions, dormers, garages, porches and balconies. Fibreglass gives a seamless finish with no joints for water to find, which matters on low-pitched or flat areas where rain can sit after a downpour.

Our GRP roofs are laid as a single-ply laminate over an 18mm OSB3 deck, finished with GRP edge trims and a protective topcoat. Grey is the usual colour, but others are available if you want the roof to blend with the house or stand out. A well-laid fibreglass roof can last 20 years or more. We fit them on the newer homes in the growing new town and on extensions behind the older village properties, as well as in Cambridge and Burwell.

Alongside our Staines head office, we have a second office covering this part of the country, including Waterbeach. Like-for-like roof work does not usually need planning permission, but if your property is listed or in a conservation area it is worth checking with South Cambridgeshire District Council before work starts, and we are happy to talk this through with you.

GRP Fibreglass Roofs FAQs for Waterbeach

Is GRP a good choice for a new extension roof in Waterbeach?

For most single-storey extensions it is a strong option. It is seamless, laid over an 18mm OSB3 deck and can last 20 years or more when installed properly. Grey is standard, with other colours available, and it works just as well for garages, dormers and porches.

Is GRP better than felt for flat roofs in Waterbeach?

GRP is seamless, so there are no joins for water to get through, and it does not need the regular maintenance that older felt roofs do. It is a popular upgrade when a felt roof fails.

What colours are available?

Most GRP roofs are finished with a grey topcoat, but other colours are available to suit your property.

What is a GRP fibreglass roof?

GRP stands for glass reinforced plastic. Resin and glass fibre matting are laid over a timber deck to form a single seamless, waterproof layer, finished with edge trims and a topcoat.

How long does a GRP roof last?

A properly installed GRP roof can last for over 20 years and shows very little sign of wear in that time.

Can GRP be laid over my existing flat roof?

Usually we strip the old covering and check the deck. If the deck is damaged or not suitable, we replace it with new OSB3 boards before laying the GRP.
